RADIATOR-FILLER CAP.

Specification of Letters Iatent. I

Patented Oct. 18, 1921.

Application filed December 4, 1920; Serial No. 428,229.

To all whom it my camera:

provements in Radiator-Filler Caps,of which the following is a specification, reference being had therein to the accompanying drawily invention aims to provide a radiator filler cap with positive and reliable means, in a manner as hereinafter set forth, for retaining a cap on a radiator filler connection or in proximity thereto, so that the cap cannot become accidentally displaced, but will be at all times on the radiator, either in a closed or opened position. The means which I employ for connecting the cap to the radiator permits of the "cap being clamped on the filling connection of the radiator to prevent the contents of the radiator from splashing outside thereof. The same clamping means afiords a" loose connection,

at times, so that the cap may-be removed from the filling connection of the radiator and set to one side thereof thus permitting of the radiator being easily filled.

My invention further aims to provide cap connecting means for a radiator or tank which may be easily and quickly manipulated and which will be concealed within the radiator or the filling connection, so that such connecting means will not detract from the general design or appearance of the radiator,

The construction entering into my invention will be hereinafter described and then claimed, and reference will now be had to the drawing, wherein-- Figure 1 is a vertical transverse sectional view of a radiator filling connection closed by a cap provided with a fastener in accordance with my invention;

Fig. 2 is a vertical cross sectional view of the same showing the cap in an open position, and c Fig. 3 is a plan of the radiator filling connection with a part of the cap fastener in a horizontal section;

in the drawing, the reference numeral 1 known farm tractor or automobile and this type of radiator or tank has an oval or oblong cap support or filling connection 2 which will provide clearance for a poured stream of water or other liquid to be placed in the radiator or tank. The cap support or filling connection 2 is ordinarily closed by a cap 3 having depending flanges 4 so that the cap may be fitted on the support 2 and revented from laterally shifting thereon.

he cap or closure 3 is somewhat crowned or bell shaped, and has a central opening 5.

Rotatable or turnable in the opening 5 of the cap 3 is the reduced inner end or shank 6 of a handle stem 7 provided with a scalloped handle or water shedding hand piece 8 by which the cap 3 may be conveniently handled. The shank 6 of the handle stem 7 affords an annular shoulder 9 by which the handle is rotatably or turnably supported on the cap 3 and this annular shoulder limits the inward movement of the handle when placed in engagement with the cap. To retain the handle in engagement with the cap the shank 6 of the handle stem 7 has an an-' nular groove in which is mounted a ring or retaining member 11 adapted to cooperate with the annular shoulder 9 inpreventing longitudinal movement of the handle stem 7 relative to the wall of the cap 3. The retaining member 11 may be in the form of a split ring snapped into the groove 10 or said retaining member may take any form which will serve as an abutment against the inner wall of the cap 3.

The shank 6 and the stem 7 of the handle 8 have a longitudinal bore or recess 12 with the walls thereof screwthi'eaded to receive the outer screwthreaded end 13 of a hookshaped connecting member, 14, said connecting member havin vided with a cross hea 15.

In the cap support or filling connection 2 is a combined stop and guide member, preferabl in the form of parallel partitions dispose in planes at each side of the minor axis of the cap support and filling connec' tion i said part tians co ecting the front its inner end proe uxtaposition of the partitions l6 affords a slot 18 through which the hook i the hook shaped shaped connecting member 14 extends, and the inner edges of the partitions 16, at the rear Wall of the filling connection 2, are recessed, as at 19 to receive the cross head 15 of the hook shaped connection member, as best shown in Fig. 2, The recessed edges of the partitions 16 afford a stop or abutment, at the rear wall of the filling connection, for the cross head 15 so that the hook shaped connecting member may be shifted to the rear wall of the filling connection and overhang the upper edge of said wall when the ca 3 is in an open' position. Otherwise, the cross head 15 engages under the lower straight edges of the parti; tions 16 and may be clamped against the partition edges by simply rotating the handle 8 to feed the threaded end 13 of the hook shaped connecting member 14 into the stem 7 of said handle. The partitions 16 afford a guide for the hook shaped connecting member 14 so that said connecting member can be easily shifted toward the rear Wall of the filling connection and said connecting member will be ordinarily moved in such direction in order that an edge of the cap 3 may rest on top of the radiator or tank l-when in an open position, as shown in Fig; 2.

On the hook shaped connecting member 14 at its threaded end 13, is a collar 20 which may be conveniently mounted on the con-- necting member by screwing it on the threaded end '13 thereof to the inner end of the screw thread, and this collar serves as an emergency stop member and also facilitates assembling the cap fastener relative to the radiator or tank 1. While the partitions 16 prevent turning of the hook shaped connecting member 13 during the rotation of. the handle 8, the collar 20 prevents the hook shaped connecting member 14 from falling into the radiator or tank 1 should the handle 8 rotated in the wrong direction to release. the hook shaped connecting member 14 relative to the handle In practice, a partial rotation of the handle 8 to unscrew the hook shaped connectingmember 14 sufficiently to release the cross head 15 relative to the partitions 16 permits of the flanged edges 4 of the cap.3 clearing the upper end of the radiator filling connection 2 so that connecting member 14 is shlftedrearwardly between the partitions 16 and then outwardly so that the cap or 010- sure 3 may assume an open position supported at an angle to the filling connection 2 by the hook shaped connecting member 14 and the top of the radiator or tank 1. I

I attach considerable importance to the p ty en t ua n n e ing into t It is thought that the utility of my invention will be apparent without further description and while in the drawing there is llustrated a preferred embodiment of my invention as now actually used, it is to be understood that the structural elements are susceptible to such variations and, modifications as are permissible by the 'appended claims. y

What I claim is 1. The combination of a tank having a filling connection, a cap, a connecting member carried by said cap, and having a configuration relative to said tank filling connection to prevent rotation of said connecting member, a hand piece extending through said. cap into screwthreaded engagement with said connecting member and adapted to cooperate with said connecting member in clamping said cap on said filling connection, and means at the inner end of said connect ing member retaining said member in the filling connection of said tank so that said cap may be tilted to one side of said tank 2. The combination of a tank having an opening, and a closure for said opening, of a guide member in the tank opening, and a connecting member carried by said cap and slidable in said guide member so that said cap may be raised and tilted at one side of said tank opening.

3. The combination set forth in claim 2 wherein said connecting member is adjustab-ly held by said closure and adapted to be,

clamped against said guide member.

' 4. The combination set forth in claim 2, wherein a turnable handle carried by said closure supports said connecting member and when turned adapted to fix said connecting member relative to said guide member.

5. The combination with a tank having an opening, and a closure for said tank opening, of partitions in the opening of said tank, a turnable handle on said closure, and a hook shaped connecting member in screw threaded engagement with said handle and extending between said partitions, the relation of sai hook shaped connecting member and said partitions being such that said connecting- 7.
